STBY I
HIGH
This alarm occurs two ways:
1) In the initial rest state after key on, if the
outputs of the current amplifiers are not
comprised in the window 2.2 to 2.8 Vdc.
2) After the initial diagnosis this alarm
occurs when the outputs of the current
amplifiers at rest have a drift larger than
±0.15 V.
It is necessary to replace the
controller.
61
HIGH
TEMPERA
TURE
This alarm occurs if the temperature of the
controller base plate overtakes 75 degrees.
Improve the cooling of the controller;
otherwise it is necessary to replace
the controller.
65
MOTOR
TEMPERA
T.
This alarm occurs only when DIAG MOTOR
TEMP is on and the thermal sensor inside
the motor measures a temperature higher
than 150 degrees. It occurs also when trying
to acquire the motor resistance with a
temperature in the motor higher than 150
degree
(still with DIAG MOTOR TEMP to ON).
Check the thermal sensor in the
motor is right working. If it is,
improve the cooling of the motor.
70
HIGH
CURRENT
This alarm occurs if the circuit to limit via
hardware the current in the motor is either
always active at key-on or repeatedly active
when the motor is turning. Check the motor is suited to work
with the eps-ac0 (not oversized).
Otherwise it is necessary to replace
the controller.
71
POWER
FAILURE
#3 This alarm occurs when the current in the
phase V of the motor is zero and the motor
is commanded for moving.
Check the power fuse is OK. Check
the battery positive arrives to the
controller. Check the continuity of
the wire in the phase V of the motor.
Otherwise it is necessary to replace
the controller.
72
POWER
FAILURE
#2 This alarm occurs when the current in the
phase U of the motor is zero and the motor
is commanded for moving.
Check the power fuse is OK. Check
the battery positive arrives to the
controller. Check the continuity of
the wire in the phase U of the motor.
Otherwise it is necessary to replace
the controller.
